Sensitivity The minimum detectable dose 髓样前体细胞抑制因子2(MPIF2)检测试剂盒of this kit is typically less than 25.5pg/mL.
Specificity
This assay has high sensitivity and excellent specificity for detection of Myeloid Progenitor Inhibitory Factor 2 (MPIF2).
No significant cross-reactivity or interference between Myeloid Progenitor Inhibitory Factor 2 (MPIF2) and analogues was observed.
Recovery
Matrices listed below were spiked with certain level of recombinant Myeloid Progenitor Inhibitory Factor 2 (MPIF2) and the recovery rates were calculated by comparing the measured value to the expected amount of Myeloid Progenitor Inhibitory Factor 2 (MPIF2) in samples.
Matrix Recovery range (%) Average(%)
serum(n=5) 79-104 88
EDTA plasma(n=5) 96-104 99
heparin plasma(n=5) 93-102 98
Precision
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Myeloid Progenitor Inhibitory Factor 2 (MPIF2) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Myeloid Progenitor Inhibitory Factor 2 (MPIF2) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%
Linearity
The linearity of the kit was assayed by 髓样前体细胞抑制因子2(MPIF2)检测试剂盒testing samples spiked with appropriate concentration of Myeloid Progenitor Inhibitory Factor 2 (MPIF2) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
Sample 1:2 1:4 1:8 1:16
serum(n=5) 78-103% 88-104% 91-98% 86-101%
EDTA plasma(n=5) 91-98% 78-94% 84-99% 91-104%
heparin plasma(n=5) 90-104% 98-105% 97-105% 84-98%
Stability
The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Test principle
The test principle applied in this kit is 髓样前体细胞抑制因子2(MPIF2)检测试剂盒Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Myeloid Progenitor Inhibitory Factor 2 (MPIF2). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Myeloid Progenitor Inhibitory Factor 2 (MPIF2). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Myeloid Progenitor Inhibitory Factor 2 (MPIF2), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Myeloid髓样前体细胞抑制因子2(MPIF2)检测试剂盒 Progenitor Inhibitory Factor 2 (MPIF2) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
